Cycle Variation in the Occurrence of Great Soft X-ray Solar Flares
V. N. Obridko, M. M. Katsova, D. D. Sokoloff
Powerful nonstationary processes such as flares and coronal mass ejections are detected mainly near the solar cycle maxima. However, the analysis of the great flares since 1975, wh…
Do Planets Affect the Behavior of the Long-term Solar Activity?
M. M. Katsova, V. N. Obridko, D. D. Sokoloff +1
Solar activity is a process driven by many independent but interconnected phenomena. Although the 11-year cycle is the result of operation of the dynamo mechanism, the cause of lon…
Resonances and Stellar Cycles: Observations and Modelling
M. M. Katsova, F. A. Azizov, V. N. Obridko +2
In the paper we discuss the possibility of the influence of parametric excitation, in particular, planetary gravitational interaction, on the behavior of stellar magnetic activity…
Is There a Synchronizing Influence of Planets on Solar and Stellar Cyclic Activity?
V. N. Obridko, M. M. Katsova, D. D. Sokoloff +1
This work continues our research of connection between the long-term activity of stars and their planets. We analyze new data on the previously considered two dozen solar-type star…
The Structure of the Solar Cycle and of the Activity Cycles of Late-Type Stars
V. N. Obridko, D. D. Sokoloff, M. M. Katsova
It is shown that the description of the solar cycle that takes into account the odd zonal harmonic of the solar magnetic field allows us to deepen our knowledge of two important as…
Relating photometric and magnetic properties of structures at solar surface
V. N. Obridko, D. D. Sokoloff, M. K. Katsova
We investigate sharp structures visible in solar magnetic field tracers. It is shown that the sunspot magnetic boundaries do not coincide with the photometric ones. Moreover, there…
